README (Thermosalinograph : MR06-05 Leg1 and Leg2)


1. Preface
----------
Thermosalinograph measures the following surface parameters continuously.
     - temperature
     - salinity
     - dissolved oxygen
Sea surface water is continuously pumped up at 4.5 meters depth to the sea 
surface monitoring laboratory and then flowed into each analysis equipment 
through a steel pipe and a vinyl-chloride pipe. 
The flow rate of this system is controlled by some valves.
